Does genetic population structure of Ambrosina bassii L. (Araceae, Ambrosineae) attest a post-Messinian land-bridge between Sicily and Africa?

2012

Abstract Aim of the present work is the analysis (through the study of enzyme polymorphism) of Sicilian and African (Tunisian) populations of Ambrosina bassii , a small perennial endemic to the Central-Western Mediterranean basin, in order to verify if the complex geological history of this part of the Mediterranean area left its mark in the present-day genetic structure of this taxon. Starch gel allozyme electrophoresis of seven putative loci of A. bassii was employed to estimate genetic diversity, genetic structure and gene flow. Populations from Sicily, Tunisia and Sardinia (as outgroup) were sampled. Results show that Sicily populations have 4 private alleles, Sardinia 3, Tunisia just o…

Fixed oil from seeds of narrow-leaved ash (F. angustifolia subsp. angustifolia): Chemical profile, antioxidant and antiproliferative activities.

2019

Fraxinus angustifolia subsp. angustifolia is a plant with an age-old use for the production of manna. However, it is also a valuable source of fixed oil rich-seeds. In the present study we examined the chemical and biological properties of this oil in order to support a possible application in foodstuffs, nutraceuticals and cosmetics. Fatty acid composition, volatile and phenolic substances were evaluated. Oleic and linoleic acid represented 45.5% and 50.0%, respectively, of the total fatty acid composition. Among polar phenolic substances identified (secoiridoids, phenylethanoid glycosides, phenolic acids and alcohols, flavonoids, coumarins) isoverbascoside is for the first time reported i…

Genetic diversity and local population structure in Ambrosina bassii (Araceae, Ambrosineae), a Mediterranean relict species

2009

The effects of habitat fragmentation on the genetic structure of Ambrosina bassii are analyzed. The species, whose reproductive biology is mostly unknown, is the only representative of its genus and tribe and it is endemic to the central Mediterranean area. The selected study area was the island of Sicily, in which wild populations show a wide morphological variability and ecological amplitude. Patterns of within- and among-population genetic diversity in eleven Sicilian populations, occurring in six disjunct areas, were examined by means of allozyme electrophoresis. High levels of genetic diversity were found as shown by the mean expected heterozygosity (He ¼ 0.263), the percentage of poly…

Assessing the genetic diversity ofCentaurea parlatorisgroup (sect.Dissectae, Compositae) in Sicily using isozymes

2011

Abstract The Centaurea parlatoris group belongs to sect. Dissectae and is one of the most taxonomically critical groups in Sicily. The taxa included in it inhabit dry slopes, pastures and rocky places. Some of them are narrow endemics to Sicily, and others to Italy. The great morphological variability at the intrapopulation level has not permitted the creation of an adequate taxonomic scheme. The recent proposal of two new species from Sicily confirms the insufficient knowledge of the taxonomic diversity. This study involves eight Sicilian populations of the C. parlatoris group. Seven loci from nine enzyme systems [isocitrate dehydrogenase (IDH), malate dehydrogenase (MDH), 6-phosphoglucona…

Morphological and genetic diversity within Pilosella hoppeana aggr. (Asteraceae) in Italy and taxonomic implications

2013

Morphological variation, ploidy level and genetic diversity have been studied on 10 populations of the Pilosella hoppeana aggr. from the Alps, Abruzzo, Calabria and Sicily.Chromosome counts showed that the plants from Abruzzo and those from Sicily are tetraploid (2n = 36); they are assigned to P. hoppeana subsp. macrantha. The plants from the Alps (P. hoppeana subsp. hoppeana) and those from Calabria are diploid. The Calabrian populations, previously included in P. hoppeana subsp. macrantha, are shown to belong to a separate species, P. leucopsilon. The principal component analysis, based on 25 morphological characters, allowed distinguishing clearly four groups. An allozymes study using 10…

On the peptidergic hypothesis for non-adrenergic non-cholinergic innervation in the rat duodenum

1992

1. The nature of the non-adrenergic, non-cholinergic (NANC) transmitter was studied in vitro in the rat duodenum, by use of an isometric-isovolumic preparation. 2. Electrical field stimulation (EFS) induced a tetrodotoxin (TTX)-sensitive fall both in luminal pressure and in isometric tension. 3. Neurotensin (NT) induced TTX-insensitive inhibitory responses similar to those induced by EFS. Vasoactive intestinal peptide (VIP) caused a delayed, slow, concentration-dependent, TTX-insensitive inhibitory effect, detected only by a change in luminal pressure. 4. alpha-chymotrypsin prevented the NT- and VIP-induced inhibitory effects and antagonized the response to EFS. 5. Apamin antagonized the EF…

Morphological observations on the reproductive structures of Ambrosina (Araceae), a Mediterranean endemic monotypic genus

2017

This research was carried out to better define the pollen, fruit and seed morphology of Ambrosina bassii , the only species of this rare Mediterranean endemic genus. Pollen traits were already known, but here we investigated on their variability in distant populations and in different morphotypes (‘varieties’). Fruit and seed traits were almost unknown, also because of the rarity of fruit-set in this species. The surface features of pollen, fruit and seed, as well as length, width and length/width ratio, were analysed by means of scanning electron microscopy (SEM). Comparative observations were made also on Arisarum vulgare , since Arisarum is the closest genus. The principal component anal…

Abstract This paper focuses on the morphology and karyology of representative Ruppia populations from a southern Mediterranean shallow system. The cosmopolitan genus Ruppia L. generally inhabits shallow waters such as coastal lagoons and brackish habitats. Ruppia species are characterised by a simplified morphology and high intraspecific phenotypic plasticity. The chromosome number of Sicilian Ruppia populations is reported here for the first time. The analysed populations showed morphological and reproductive characters of Ruppia cirrhosa (Petagna) Grande but a diploid cytotype (2n = 20). A low fruit production was also observed, suggesting that vegetative reproduction is the main reproduc…

Ethnobotany of dye plants in Southern Italy, Mediterranean Basin: floristic catalog and two centuries of analysis of traditional botanical knowledge …

2020

Abstract Background Since ancient times, man has learned to use plants to obtain natural dyes, but this traditional botanical knowledge (TBK) is eroding. In the late, during, and the early 1800s, there was an increase in research related to dye species, and this allowed the development of industry and economy in rural contexts of Southern Italy. Today, dyes are mainly obtained from synthetic products, and this leads to risks for human health related to pollution. Methods Starting from the literature, three catalogs of the dyeing species (plants, algae, fungi, and lichens) used in the Mediterranean Basin and mainly in Southern Italy have been created. Percentages of parts used and colors ext…

Chemical composition and microencapsulation suitability of sumac (Rhus coriaria L.) fruit extract

A contribution to the characterization of Ruppia drepanensis (Ruppiaceae), a key species of threatened Mediterranean wetlands

2021

To elucidate the taxonomic status of Ruppia drepanensis Tineo ex Guss. (Alismatales, Ruppiaceae), we performed morphological analysis and DNA barcoding of historical materials (including the lectotype) and fresh samples (including those from a recently discovered population near the locus classicus in Sicily, Italy). We conclude that R. drepanensis is a separate species, closely related to R. spiralis L. ex Dumort., that occurs in temporary inland waters from the western to central sectors of the Mediterranean region. We also highlight the importance of vouchers and the need to link molecular investigations to field, ecological, and morphological investigations.

Notes on the karyology, genetics and ecology of Genista sect. Voglera in Sicily

2012

To investigate the biosystematic and genetic relationships among Sicilian species of Genista sect. Voglera, four populations of three species, Genista aristata C. Presl, Genista cupanii Guss., and Genista madoniensis Raimondo, have been studied. Genista madoniensis is tetraploid, with a chromosome number of 2n = 48, as are the other two species. An isozyme study showed that G. madoniensis is taxonomically closer to G. aristata than to G. cupanii, the latter possessing four unique alleles. The results are discussed in the context of the ecological characteristics of each species.

Genetic relationships between Sicilian wild populations of Brassica analysed with RAPD markers

Brassica, species related to kale crops form a complex group. The genetic relationships among 15 populations occurring in Sicily and one from Calabria, representing the existing diversity, have been investigated using random amplified polymorphic DNA (RAPD) markers. This assay, carried out with 22 arbitrary primers, generated 236 polymorphic fragments, 21 of which were specific for single populations (mainly Brassica insularis, Brassica incana and Brassica macro-carpa). Jaccard's genetic distances were computed and the phylogenic tree was establishe…

Isozyme analysis of genetic diversity in wild Sicilian populations of Brassica sect. Brassica in view of genetic resources management

2004

In Sicily and in the small surrounding islands the section Brassica of the genus Brassica comprises five species, B. insularis Moris, B. incana Ten., B. macrocarpa Guss., B. rupestris Raf. and B. villosa Biv. These taxa represent a genetic resource as relatives of kale crops but some populations are endangered or threatened, thus isozyme analyses were performed to assess the genetic diversity degree at population and species levels in order to assist the design of conservation management programs. Eleven loci from five enzyme systems (aconitase, leucine aminopeptidase, 6-phosphogluconate dehydrogenase, phosphoglucoisomerase phosphoglucomutase) were analyzed in sixteen natural population (fi…

Neurotensin (1 pM to 10 nM) induced a concentration-dependent, tetrodotoxin (TTX)-insensitive fall in both endoluminal pressure and isometric tension. At higher concentrations of neurotensin (1 nM to 1 microM) the relaxation was followed by a concentration-dependent TTX-insensitive contraction, detected only by an increase in endoluminal pressure. Different concentrations of neurotensin were required to desensitize the relaxant and the contractile actions of the neuropeptide. The relaxation was antagonized by apamin, while the contractile response was blocked by nif…

Ethnobotanical uses of wild taxa as galactagogues in Sicily (Italy)

2018

<p>Breastfeeding furnishes optimal nutrition, immune support, and a multitude of health benefits to mothers and newborns. Since ancient times plants have been employed as galactagogues in the folk medicine of many human cultures. In Sicily, a region with great floristic diversity in the Mediterranean area, where a conspicuous pool of species is traditionally used for food and aromatic, cosmetic, handicraft, agricultural, forestry, and medicinal purposes, some people recognize the galactagogue properties of some spontaneous plants.</p><p>The goal of this study was to identify wild plants with galactagogue properties and vegetable-food remedies traditionally used by women du…

Brassica tardarae (Brassicaceae), a New Species from a Noteworthy Biotope of South-Western Sicily (Italy)

2020

A new species of Brassica sect. Brassica is described here from Sicily (Italy), which is known to be one of the centers of the diversification of wild taxa of this group. The new species (named Brassica tardarae) is restricted to the carbonate cliffs in the Tardara Gorges between Menfi and Sambuca di Sicilia (Agrigento province), an area with a peculiar geological history and where another strictly endemic species was recently described. The morphological relationships between the new species and other similar taxa are discussed, and an analytical key to the Sicilian taxa belonging to the genus Brassica sect. Brassica is also provided.

Chemodiversity of the Essential Oil from Leaves of Abies nebrodensis (Lojac.) Mattei

2016

Abies nebrodensis (Lojac.) Mattei (Pinaceae) is a species occurring in a very small population only in a restricted area of Sicily. Its taxonomic classification as different species has been object of discussion. In this work the chemical composition of the essential oil from the leaves is presented for the first time and compared to the essential oils from other euroasiatic species reported in literature. Peculiar characteristics of the essential oil of A. nebrodensis are highlighted.
